A network architect is proposing this solution to a customer. The customer network manager has a preference for Cisco VLAN Spanning Tree Plus (PVST+) because this protocol provides for fast convergence when a link fails and also provides per-VLAN load-sharing over links.
How would the network architect explain why the solution fits these requirements?
AThe MSTP component of the solution fulfills the same needs as PVST+ MSTP simply balances traffic per instance rather than per-VLAN

CThe solution as shown provides the same load-sharing benefits as PVST+. To achieve the same resiliency benefits, the architect can add smart link to the meshed stack
DThe link aggregation between tiers provide even better resiliency and load-sharing than PVST+ while MSTP protects against accidental loops

A network architect is designing the logical topology for a campus LAN networking solution. The customer requires support for 2400 edge ports, which is provided by 10 intelligent Resilient Framework (IRF) groups at the access layer. This customer does not have a wireless network nor anticipants adding one in the next two years. However, the customer does want to authenticate users with 802.1X and use the network RADIUS server to divide users from different groups into different
VLANs. The customer has three user groups, each of which includes between 600 and 900 users.
Additionally, the customer understands that the RADIUS server will require several policies but wants to keep these policies as simple and easy to maintain as possible.
How can the network architect ensure that the solution meets the customer needs and also follows best practice?
AAssign a /23 subnet to each VLAN so that the VLAN can accommodate the required number of users, even if users connect multiple devices
BPlan a different VLAN ID and subnet address for each user group on each access layer IRF group. Either core or access layer routing will work for this solution
CUse access layer routing. Assign a different subnet to VLAN2 on one access layer IRF group then the VLAN2 on the another access layer group
DPlan a solution for designing dissolvable agents to the endpoints so that they can complete 802.1X authentication seamlessly
